Margin <-> markup converter API

Convert between margin and markup (markup = margin/(1−margin); margin = markup/(1+markup)) and, given cost, derive price and profit per unit. Deterministic pricing conversion agents commonly confuse. Answers 'convert margin to markup','what markup gives a 40% margin','price from cost and markup'.
